They are.. I just didn't write up the mechanic for it.. and I'd have to write up a knowledge check to know that.. I wrote this up in an hour, I'm allowed to miss something. I'll fix it later.Think called shots to an open mouth are s special vulnerability or just a more regular thing?
If the weapon is powerful enough.. vaporizing the head and neck would kill the Titan. Otherwise, treat it like a giant troll.. massive regeneration capability (which can take time), once the titan is wounded enough and goes down, gives the mech pilot time to slash the vulnerable spot, IF they know about it. Otherwise, the Titans would just come back with same numbers while mech pilots have to repair and rearm.I am wondering how well common mecha would perform against the Titans from Attack on Titan. Now I haven't actually watched the anime or read the manga, but Titans only have one weakspot- the nape of the neck, right? Even if you have like a hyper-impulse cannon, if you don't hit that spot, the Titan will keep coming. Still it seems possible to penetrate their skin easily enough, with the right weapon. In theory a beam rifle could pierce all the way through a Titan's neck. Ultimately, my assessment would be that they would be a fairly formidable opponent for most mecha, but not an insurmountable one.
Yup, some of them run quite hot. Purposely and some not so. So the heat can be used as a weapon or defensive measure. Some have heavy bone plating. Some can generate 'armour' or harden their skin in select areas, to either protect the nap or other areas, or to add bonus damage to melee strikes. A few other uses as well.There are other details that may come in handy like they run pretty hot (maybe a bonus to track them using thermal sensors?)
If I recall, Dark Heresy doesn't use the d20 system.. so converting can be a little tricky.. If you know of the item(s) you want to adapt, let me know, I can find some info on it/them in the Lexicanum wiki, or you can PM me the book stats and info and I can convert.BTW, concerning the fact that we have done 40K stuff here... I own a few of those books from the 40K RPG line (Dark Heresy, Rogue Trader and the like). I was thinking about trying to adapt s couple of the gizmos for this thing using the stuff already statted as a baseline.
